friendly_id gem for current_user

Question

我一直在想如何使用current_user user_name作为它们的url。目前看起来像http://localhost:3000/users/2而不是http://localhost:3000/users/user_name。所有的帮助表示赞赏。如有任何问题，请询问。

User.rb

class User < ActiveRecord::Base 
extend FriendlyId 
friendly_id :user_name, use: :slugged 

用户控制器改变所有@user = User.friendly.find（PARAMS [：ID），如下所示。不是整个列表，但你可以看到我的意思。

class UsersController < ApplicationController 
    def index 
    @user = User.new 
    if @current_user 
    @leaders = @current_user.leaders 
    end 
    end 

    def create 
    @user = User.new(user_params) 
    if @user.save 
    session[:user_id] = @user.id 
    cookies[:user_id] = @user.id 
    flash[:notice] = "Welcome" 
    redirect_to "https://stackoverflow.com/users/#{ @user.id }" 
    else 
    flash[:alert] = @user.errors.full_messages 
    redirect_to "https://stackoverflow.com/users/new" 
    end 
    end 

    def new 
    @user = User.new 
    end 

    def edit 
    @user = User.friendly.find(params[:id]) 
    current_user 
    end 

    def show 
    @user = User.friendly.find(params[:id]) 
    if current_user 
    @followerlink = DateRate.where(leader_id: @user.id, 
           follow_id: current_user.id).first 
    @reverselink = DateRate.where(leader_id: current_user.id, 
           follow_id: @user.id).first 
    end 
    end 

    def update 
    @user = User.friendly.find(params[:id]) 
    if @user.update(user_params) 
    flash[:notice] = "Updated profile" 
    redirect_to "https://stackoverflow.com/users/#{ @user.id }" 
    else 
    flash[:alert] = @user.errors.full_message 
    end 
    redirect_to "https://stackoverflow.com/users/#{ @user.id }/edit" 
    end 

模式

create_table "users", force: true do |t| 
    t.string "user_name" 
    t.string "email" 
    t.string "password_digest" 
    t.text  "about_me" 
    t.string "slug" 
end 

add_index "users", ["slug"], name: "index_users_on_slug", unique: true 

如果我要为了增加更多的文件有一个更好的了解，请让我知道。感谢您给予的任何帮助。

Answer 1

常，它应与

user_path(current_user) 

但更具体，试试这个工作，

user_path(current_user.to_param)

# construct your edit form with post method for this to work 
post "https://stackoverflow.com/users/:user_name/update", to: "users#update"

您应该使用user_path（ID：user.name）或edit_user_path（ID：user.name），例如，以用户的URL
